Abstract
The invention relates to a safe and efficient hoisting device for an electric locomotive, which solves the problems of high labor intensity, low efficiency, potential safety hazard and the like in the conventional manual lifting method during maintenance of the underground electric locomotive. The invention comprises a bracket, wherein two ends of a bracket beam are respectively provided with a chain block with a transmission chain and a hoisting chain, the hoisting end of the hoisting chain is provided with a hook, a motor is respectively and fixedly arranged below each chain block, and a chain wheel on an output shaft of the motor is connected with the transmission chain on each chain block; a controller for controlling the rotation direction and the rotation speed of the motor is arranged beside the motor. The device has the advantages of simple structure, reliable use, small maintenance workload, low modification cost and high safety factor. The device not only reduces the labor intensity of the repairing workers of the underground electric locomotive, but also improves the mechanization level of hoisting repair, and ensures the safety and high efficiency of hoisting and overhauling of the electric locomotive.
Description
Technical Field
The invention relates to the technical field of underground vehicle maintenance, in particular to a safe and efficient hoisting device for an electric locomotive.
Background
An electric locomotive repair workshop is generally arranged under a coal mine and used for performing tasks such as regular inspection, maintenance and the like on electric locomotives. In the process of regular inspection and maintenance of the electric locomotive, a safe and reliable hoisting device is needed to lift the electric locomotive so as to carry out the task of regular inspection and repair, the hoisting or the lowering of the existing electric locomotive is completely completed by manually dragging a transmission chain of a chain block, and the hoisting mode has the problems of high labor intensity, low efficiency, potential safety hazard and the like.
Disclosure of Invention
The invention aims to solve the problems of high labor intensity, low efficiency, potential safety hazards and the like of the existing manual lifting method of the underground electric locomotive, and provides a safe and efficient lifting device for the electric locomotive.
The invention is realized by the following technical scheme:
a safe and efficient hoisting device for an electric locomotive comprises a support, wherein two ends of a cross beam of the support are respectively provided with a chain block, the chain blocks are provided with a transmission chain and a hoisting chain, the hoisting end of the hoisting chain is provided with a hook, a motor is fixedly arranged below each chain block, an output shaft of the motor is provided with a chain wheel, and the transmission chain on each chain block is respectively wound on the chain wheels of the motors right below the chain block; a controller for controlling the rotation direction and the rotation speed of the motor is arranged beside the motor.
The transmission chain, the hoisting chain and the motor on the chain block form a lifting electric transmission system, and the controller is used for controlling the motor to realize reversing and stepless speed change so as to reliably finish the lifting and lowering work of the electric locomotive.
When the device is used, the device is arranged right above a locomotive track in a repair workshop, the chain block is perpendicular to the central position of the locomotive track, the motor is fixedly arranged at the position, away from the track, of not less than 500mm, then the electric locomotive to be repaired is stopped below the device, a hook on a lifting chain of the chain block is used for stably fixing the electric locomotive through a steel wire rope sleeve, the rotation of the motor is controlled through an operation controller, so that a transmission chain of the chain block and the lifting chain are driven to lift the electric locomotive, and the electric locomotive can be inspected and repaired at the moment; after the inspection and maintenance of the electrified locomotive are finished, the rotation of the motor is controlled by operating the controller, so that the transmission chain and the lifting chain of the chain block are driven to put down the locomotive. Therefore, the transmission chain on the chain block and the motor form a lifting electric transmission system, the motor is controlled by the controller to realize reversing and stepless speed change, and the lifting and lowering work of the electric locomotive is reliably completed.
The device has the advantages of simple mechanism, reliable use, small maintenance workload, low modification cost and high safety factor. The device not only reduces the labor intensity of the repairing workers of the underground electric locomotive, but also improves the mechanization level of hoisting repair, and ensures the safety and high efficiency of hoisting and overhauling of the electric locomotive.

FIG. 1 is a schematic structural diagram of the present invention.
In the figure: 1-beam, 2-chain block, 3-drive chain, 4-hook, 5-motor, 6-chain wheel, 7-controller, 8-hoisting chain.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1, a safe and efficient hoisting device for an electric locomotive comprises a support, wherein two ends of a cross beam 1 of the support are respectively provided with a chain block 2, the chain blocks are provided with a transmission chain 3 and a hoisting chain 8, a hoisting end of the hoisting chain 8 is provided with a hook 4, a motor 5 is fixedly arranged below each chain block 2, an output shaft of each motor 5 is provided with a chain wheel 6, and the transmission chain 3 on each chain block 2 is respectively wound on the chain wheels 6 of the motors 5 right below the chain block; a controller 7 for controlling the rotation direction and the rotation speed of the motor 5 is arranged beside the motor 5.
During specific implementation, the support is fixed right above a locomotive track in a repair workshop, the chain block 2 is perpendicular to the center position of the locomotive track, and the motor 5 can be an air compression motor (realizing waste recycling and reducing cost) on a scrapped electric locomotive and is fixedly installed at a position, which is not less than 500mm away from the track, by using a high-strength bolt.
